Revocable Life Trusts, as with all trusts, don't go through probate. This means that you can keep contents of the trust confidential, there are fewer delays in distribution of your assets, and there's also less of a risk that the distribution of your assets will be challenged.
With a trust, you gain better control of how and when assets are dispersed. By imposing limitations and restrictions to how your estate is distributed, you can be sure that your assets are used in an approved manner.
And finally, a Revocable Life Trust it's just that- it's revocable. If you change your mind and decide to remove any assets from the trust, change who the beneficiaries are, or adjust any term, you can do so without penalty.
